[0003] The dyeing and / or lightening product may comprise at least one dye composition and at least one developer composition. For best results, the dye composition and the developer composition may be placed in a multi-compartment package and mixed immediately before use.

[0004] When using hair dyeing and / or lightening products, particularly for home use, consumers often expect ease of application. Foam dyeing and / or lightening products are becoming very popular due to their ease of application. However, it is difficult to dye and / or lighten hair with a foam while achieving balanced performance in terms of good foaming ability without dripping.

[0005] Therefore, there is a need for a hair dyeing and / or lightening product that can deliver a rich lather to the hair without dripping problems.

[0006] The formulation of environmentally friendly cosmetic products, which are designed and developed taking environmental issues into account, is becoming a major objective in an effort to meet global challenges.

[0007] It is therefore essential to propose more sustainable compositions, preparation processes and ingredients to address these environmental concerns.

[0008] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or materials with a good carbon index. naturalness and / or materials of natural origin, and more particularly, materials of plant origin, while reducing the use of petrochemical compounds. Summary of the invention

[0012] B. a developer composition comprising at least one surfactant;

[0013] wherein the colorant composition and the developer composition are mixed by an external force prior to use to generate a foaming mixture.

[0014] The inventors have discovered that rich foams can be formed with the kit according to the present invention and applied to keratinous materials without any problem of dripping.

[0015] In some preferred embodiments, the foam produced by the kit according to the present invention is stable.

[0016] According to a second aspect, the present invention proposes a method for dyeing and / or lightening keratinous fibers, comprising:
